I'm looking at an asp.net application, i notice that there are assemblies defined into two places. In web.config there is configuration/system.web/compilation/assemblies/add elements. In the project file there are references setup under the Project/ItemGroup/Reference elements.
I was wondering, what is the difference between assemblies/references added in either location?
when I reference a assembly. It's reference gets added to the project file in my case ( ABC.csproj)
Also when I take a look at the web.config file there is a section called <assemblies>. And lot of assemblies are added there.
What is the difference between link to the assemblies in the Project file and the assemblies in the web.config file?
I am trying to break a large web.config file into smaller parts. This has been covered a few times on different stack overflow questions (like this or this) which recommend using the configSource or file attributes. The problem is this does not work for the system.webServer section used to configure IIS 7 in integrated mode. This is particularly bad for web.config files that have IIS Rewrite rules which tend to bloat the files.
View 1 RepliesThe httpRuntime element configures ASP.NET HTTP run-time settings that determine how a request for an ASP.NET application is processed.
Is it a good idea to customize this element in the config file.
The user has indicated that the application seems to be kicking her out, even though she is sure that she is submitting a form faster than every 30 minutes.
My Config file has these vales set, am I missing anything?

Is there a way to retrieve values from the form object using the id element instead of the name element?
View 3 RepliesI have a table in ASP.Net like this.
[code]....
I want to give border line to first td element which contains the colspan and rowspan. Not to the entire row.
I have noticed that when I create a website in a network drive and use the Ajax toolkit I get :
Element 'ToolkitScriptManager' is not a known element
I also noticed that after adding the ToolkitScriptManager it doesn't add the ID in the source code, it looks like this:
<asp:ToolkitScriptManager runat="server"></asp:ToolkisScriptManager>
Is missing the ID="ToolkitScriptManager1" part.
This doesn't happen when I create the site in my local drive. Is there a workaround to this. Even if I add the missing parts, I keep getting the same error.
I would like to select an element that is in the same TR as another element I found with a selector. The selector itself: $("input[name='sMessageValue']","#messageTable") Now I have this element and got its value I would like to find a checkbox located in the same TR, i tried this as starting point : $(this).(':parent').val(). But seems not the right thing to do.
View 9 RepliesYou're making a website with ASP.NET 4.0/C#, although xml alone is suitable for this example. The site will have a site map and a default page with a menu control, as follows:Web.sitemap
<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >

I'm working on an EmailSender, and I'm grabbing the email address from my Web.config file. I'd like to also grab a "display name" for that email, from the same section if possible, but I'm not seeing an obvious way to do this. In my Web.config file, I have included a default "from email address", like this:
<configuration>
<[URL]>
<mailSettings>
<smtp from="[URL]><!-- no displayName attribute :( -->
<network ... />
</smtp>
</mailSettings>
</[URL]>
</configuration>
In my EmailSender, I have something like this:
var smtpSection = ...;
var message = new MailMessage();
message.From = new MailAddress(_settings.From, senderDisplayName);
Is there a recommended way to store senderDisplayName in a web.config file? Is there some way to include it in the from attribute? For example:
<smtp from="Automatic Mailer [URL]">
Or does it need to be a custom element in appSettings? Or is there some other way?
Element 'content' is not a known element. this can occur if there is a compilation error in the website, or the web.config file is missing.
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:Content --- showed a green wavy line , and on hover displayed the above error.
Now I am having certain problems.
1. Visual Studio 2010 hangs when I try to use ToolBox.
2. Intellisense for asp.net controls is not working.
I have tried replacing web.config file (frm backup) , tried to debug - it doesnt show anything.
All other websites are working alright. Have problem with only one of the websites.
I upgraded from VS 2008 to VS 2010 and now the AJAX elements are not recognised by the source code editor, e.g. UpdatePanel, ScriptManager, etc. I get warnings in VS and no intellisense for those elements. When I run the site, all the AJAX controls work OK though.
View 6 RepliesI have a <div> element in a web page. I've assigned it an "ID" and made it a server-side control by using "runat=server". How do I define that <div> in the code-behind. I'm been looking at the "System.Web.UI.HtmlControls" namespace and not sure what to use. The reason I need to do this is because within this <div> is a "Submit" button which will cause a postback. When I click the submit button the first thing it does is it executes a procedure to perform edit checks on the various textbox controls. If a control is empty, a message pops up. When the user clicks "Ok" for the message, the <div> disappears because when the form loads, the <div> style.display property is set to "none" by default. Basically, all I want is for the <div> not to disappear when the edit checks are performed and a messagebox pops up.
View 7 Replies my .aspx page a have this HTML element:
<table id="table7" runat="server"></table>
I want to use C# to put some rows inside ...
Of course, I chould do this:
table7.Rows.Add( ... );
But the problem is, I create the ID dynamically and I have multiple tables with IDs like "table1","table2", and so on....
string idFromDB = ... // retrieve the number from the database
string fullId = "table" + idFromDB;
HtmlTable tbl = .... get the element based on fullId .... ??????
tbl.Rows.Add( ... );
How do I reference the table element by the ID?

View 1 RepliesNow since i'm securing the site i've noticed that the location element does not get much attention.The only thing i have found is that you can use <location path="" allowOverride="false"> on machine.config .I'm not sure how this goes but if you need to use this one every page then i will have multiple problems.First if i have a page with the same name on another website there is trouble and also if i need to update pages again problem.What i'm not sure of is if the location element on machine.config i just used once and then magically every site you have will throw an exception if a hacker changes you web.config.I have doubts and it's confusing and if i play with the server web.config,well i don't wanna mess with that.
So i also tried to encrypt the location element but i cannot find an example(can you encrypt it?).I can encrypt authorization and authentication but i will not go inside the location element.Just the standard authorization and authentication nodes.How can i secure the web.config location element so no hacker can change the allow,deny,etc.

I got this errors while trying to use an example from the ASP.NET 3.5 Unleashed book.
Webform1.aspx
[Code]....
LengthValidator.cs
[Code]....
As from the book's note, I think I added this line correctly:
[Code]....
However, the compiler kept complaining that:
Warning 1 Element 'LengthValidator' is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing. C:Visual Studio 2010 ASP.NET ProjectsWebApplicationFourWebApplicationFourWebForm1.aspx 16 17 WebApplicationFour
I am using dotnetCHARTING: the dll is installed in the GAC and referenced in my web.config (all versions appear to match). The project has a reference to the dll.
web.config:
<add assembly="dotnetCHARTING, Version=5.3.3540.17054, Culture=neutral, PublicKeyToken=af2cd47db69d93bd"/>
The site code compiles ok, but all aspx pages using the charting library complain that the Chart tag does not exist (warning that it might be a compile error). The aspx pages do not render the charts.
Each page has a reference to the assembly:
<%@ Register Assembly="dotnetCHARTING" Namespace="dotnetCHARTING" TagPrefix="dotnetCHARTING" %>
What does that means below warning:
Element 'AsyncPostBackTrigger' is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing.
My app is working properly but visual studio showing warning like that.
Element 'ScriptManager' is not a known element. This can occur if there is a compilation error in the Web site.
Element 'UpdatePanel' is not a known element. This can occur if there is a compilation error in the Web site.

Element 'TextBox' is not a known element. This can occur if there is a compilation error in the Web site.
In my ASP.NET's Web Config file I have the following location elements defined:
<location path="">
<system.web>
<authorization>
<deny users="?"/>
</authorization>
</system.web>
</location>
<location path="dir1">
<system.web>
<authorization>
<allow users="?"/>
</authorization>
</system.web>
</location>
<location path="dir2">
<system.web>
<authorization>
<allow users="?"/>
</authorization>
</system.web>
</location>
The example above is specifying that all directories will be locked down to anonymous users except the two directories dir1 and dir2. I'm curious if there is a syntax that I can use that will allow me to define more than one directory within one location element. For example, it would be convenient if we could do something like this...
<location path="dir1,dir2,etc">
<system.web>
<authorization>
<allow users="?"/>
</authorization>
</system.web>
</location>
How to specify multiple paths in one location element in web.config:, a
<location path="Images">
<system.web>
<authorization>
<allow users="?" />
</authorization>
</system.web>
</location>
We would like to add styles and images to location, e.g. location path="images, styles". Is it possible to put multiple paths in location element (and how)?
I'm having some trouble setting the ExecutionTimeout element in my applications web.config. My page is making a lengthy webservice call and times out after 110 seconds. (the default I believe). I set the value to 220, and make sure the compilation debug=false.
Does the compilation setting refer to when IIS/ASP.net compiles the ASPX pages when a client requests them, or does it refer to the visual studio compile process there the assemblies are created. Would using an assembly built using debug in visual studio still allow the above settings to work?
I need to read configuration elements from the web.config. Let this be my web.config.

<child name="Hello"/>
<child name="World"/>
</parents>
<parents>
<child name="Hello1"/>
<child name="World2"/>
</parents>
</family>
So I have something like this, I need to read this into a collection.
Here is the contents of my test.ascx file:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="test.ascx.cs" Inherits="UserControls_test" %>
<p id="XXX">aaa</p>
and here is the contents of my test.ascx.cs file:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class UserControls_test : System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
this.XXX.InnerHtml = "BBB";
}
}
I get an error when I refer to the id, "XXX" (underlined above) in code behind which reads: 'UserControls_test' does not contain a definition for 'XXX' and no extension method 'XXX' accepting a first argument of type 'UserControls_test' could be found (are you missing a using directive or an assembly reference?)
I have tried XXX.InnerHtml and I have tried this.XXX.InnerHtml and get same problem.
How do I successfully refer to ID'ed HTML elements in code behind?
